Our customers no longer have to compromise between noise reduction, sound isolation, sound absorption, or EMI RF shielding based on Faraday cage technology. IAC's reliable technical solutions, proven for decades, are today the "gold standard" of any clinic or university. We provide unsurpassed quality and comfort for research and are used in many areas of medicine and science.
EMI Waves Attenuation in audiology shielded booths
Shielding effectiveness (SE) testing of electromagnetic compatibility (EMC) field shares some similarities with airborne noise reduction measurements.
SE represents the relative attenuation value for different types of electromagnetic wave radiation, including Electric Field (E-Field), Magnetic Field (H-Field), and Plane Waves. The standard EN 50147-1 outlines the typical method for shield attenuation testing. However, challenges arise when dealing with a variety of audiometric and screening testing such as ERA / BERA or animal brain testing. These specialized applications require an extended frequency range for shielded chambers, compliance with hospital regulations, consideration of acquisition system sensors, and other related issues. Drawing upon our extensive expertise of over 50 years in designing shielded rooms for audiometry, we offer our esteemed customers a range of standard and customized options for shielding effectiveness, as shown in Graph 1a and Graph 1b in EMI / RF shielded acoustic rooms brochure.
Consideration of environmental EMI conditions is crucial, particularly when it comes to ensuring effective magnetic H - Field protection. For shielded EEG rooms focused on different human body measurements, the inclusion of shielded windows Is required. A substantial open area poses challenges in terms of shielded enclosure orientation during installation at hospital or university sites. Transparent materials such as copper mesh, stainless steel mesh, or shielding foil exhibit inadequate magnetic low-frequency attenuation compared to the superior performance offered by classic IAC Moduline Noiselock® galvanized panels. The larger the surface area covered by the mesh entails the higher the risk of unwanted radiation infiltration, which can significantly impact measurement accuracy and bring unwanted artifacts. Thus, careful consideration should be given to the choice of RF / EMI shielding materials and their impact on the overall effectiveness of magnetic H - Field shielding in diverse EMI conditions.
Shielded floor construction
IAC Acousti-flote™ floors shall be 50mm or 90 mm high and structurally reinforced. All floors are carpeted. Average weights are no less than 90kg/m2. Floors float on properly loaded vibration isolators rated for a natural frequency of 6.5Hz for maximum elimination of structural noise. Discover our flexible solutions tailored to meet our clients' needs. With the ability to combine and utilize various types of shielding materials and false floors, we ensure the achievement of your desired level of shielding.
